Arterio-Venous Aneurysma of the Lung

Cerebral abscess in hereditary haemorrhagic telangiectasia: report of two cases in a family.

“…Maier, Himmelstein, Riley, and Bunin (1948) and Stevenson (1953) have suggested that infection could arise in the pulmonary arteriovenous fistula itself, which then discharges septic emboli, but such 'endocarditis' has not been demonstrated histologically. Often a primary source of infection cannot be found (Table I), but a number of cases have suffered from bronchitis, as in case 2, or chronic osteomyelitis (Muri, 1953). The absence of antecedent infection and the preferential localization in the brain with no abscesses at other sites has also been commented on in congenital heart disease (Sancetta and Zimmerman, 1950).…”

Pulmonary Arteriovenous Fistula: Presentation, Diagnosis, and Treatment

“…Pulmonary arteriovenous fistulas (PAVFs) are vascular malformations that represent direct communications between the pulmonary artery and vein without an intervening capillary bed. They occur with an incidence of 2 to 3 per 100,000 population [1] and have been described under a variety of pseudonyms including benign cavernous hemangioma, pulmonary arteriovenous angiomatosis, hamartomatous angioma of the lung, arteriovenous aneurysm and pulmonary arteriovenous malformation [2,3]. Females are more often affected than males [4,5].…”
